Many thanks for this. I have read and understand the "Interoperability 
Tutorial" which uses the "driver_output" function, but when looking in 
the documentation on this function - it did not label this funciton as 
thread safe. I asked because this seemed like a pretty big "hole" given 
the elegance in the rest of Erlang (i.e. I guessed I had missed something)

I will look into this, thanks.
